Opioid abuse initiates specific protein interactions in neurons in brain's reward system

New research reveals that opioid use changes the activity of a specific protein needed for normal brain function, affecting both pain relief and tolerance. The study found that blocking this protein can reduce addiction-related behaviors, but increasing its activity lowers pain relief response and leads to faster morphine tolerance.
